Description
This experiment module illustrates Bernoulli’s equation as applied to a convergent-divergent duct. A Pitot static tube measures both the total pressure and the static pressure independently. The tube traverses along the axis of the duct and connects to the Manometer (ancillary) via flexible tubes fitted with quick-release couplings. A clear scale printed on the duct helps to show the probe position. Students confirm the constant total pressure while observing the rise and fall of the static pressure. They compare the velocity-area ratio as calculated from Bernoulli’s equation to the experimental results.
Features
- One of a series of eight experiment modules that fi t to the Modular Air Flow Bench
- Quickly and simply illustrates Bernoulli’s equation for air, and its limitations due to boundary layer effects
- Toggle clamp connections to the Modular Air Flow Bench contraction for quick and easy fitment
- Quick-release couplings for rapid and reliable pressure connection to the Manometer
- Transparent front to the duct so that the profile of the test nozzle and the position of the Pitot static tube can be seen clearly
